The CY7C68013A (FX2LP) is a high-speed USB 2.0 peripheral controller from Infineon (formerly Cypress Semiconductor). It integrates an enhanced 8051 microcontroller with a programmable Quantum FIFO memory interface. This architecture enables high-bandwidth data transfers without intense CPU intervention, making it a staple for logic analyzers, SDRs, and custom data acquisition systems. Architecture Overview
The FX2 becomes the master. You program a waveform into the GPIF unit to generate custom control signals.
